For me several games still run quite slow in Unity, but run okay in Unity 2D or
on a seperate X-server.
Recent examples are Dustforce and Oil Rush. For example Oil Rush with
ultra/high has 53 fps in the main window on a seperate X-server but only has 33
fps and sluggish mouse cursor under unity.

Alejandro Pulver, I haven't reported any new bugs related to compiz or
unity.
I think I should report at least two new bugs.
One for low FPS and the other for none constant FPS.
This behavior is very visible in apps like xbmc or vdr-sxfe.

Moses, all, please do not switch drivers while testing fixes for this
bug. The performance bottlneck is in Unity itself so to accurately test
fixes to unity you need to keep a stable baseline (the same driver).

I can confirm the observations made by Achim.
I first tried the PPA with nouveau, and did not notice any visible
change.
When I activated the binary nvidia driver, however, the change was quite
obvious. The slowdowns are not entirely gone, but they disappeared for
the expo animation entirely, and
Could it be that something in NUX is responsible for the rest of the
performance regression?
I have attached a perf report, that I recorded while I was running ioquake3.
So I am not an expert in such thing but I hope this report is somehow helpful.

Stefan, this bug would affect all apps. Windowed and fullscreen. 3D and

experiencing the bug will find this one and not log duplicates. Because
you generally only notice frame rate problems in 3D apps.

Is it possible that the general slowdown of (windowed?) OpenGL-apps is

Hi Daniel,
I bisected the source code of Unity a little and i think i've found at
least one revision which is causing the slowdown:
rev. 2226:
* Fix for bug #839480
* Fix rendering of the Dash, Launcher and Panel when "NO_BLUR" is selected in
CCSM
* Added support to get a none blurred r
Thanks Moses. It sounds like this is definitely the bug causing your

1. Slight pauses in animations: That could be this bug (Unity interfering in
compiz GL rendering too much), but it could also be related to switching
rendering modes during animations. Please try this as a workaround:

I have the same issue I think.
Any animation in Compiz, when using the nvidia driver and not nouveau

movements". That is, the movement is very smooth, but it stops randomly.
